MOUNTING FOR (EASTER-WHEELS.

Application filed November 17, 1909.

To all whom it may concern:

Be it known that I, Janus SHARON, a citizen of the United States, and a resident of Canaseraga, in the county of Allegany and State of New York, have invented a new and Improved Mounting for Caster-WVheels, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a mounting for a caster wheel which may be placed in an operative and inoperative position successively, and held in each position securely; to provide a mounting which may be quickly and readily adjusted to form a solid bearing for the caster; and to provide a mounting of the character specified which is simple, durable and economical of construction.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a vertical section of a stove leg having a caster mounted therein, and constructed and arranged in conformity with the present invention, the caster being illustrated in the inoperative position; Fi 2 is a view similar to that shown in Fig. 1, the caster being arranged in operative position; Fig. 3 is a cross section of the stove leg and mounting taken on the line 33 in Fig. 2; and Fig. 1 is a side View of a fragment of the stove leg illustrated in Fig. 1, showing the caster and mounting therefor as drawn outward from the position shown in said figure.

The stove leg 5 illustrated in the drawings resembles in the essentials of construction the usual stove leg. It differs in having cast thereon lugs 6, 6 and a seating lug 7. The lugs 6, 6 conform to the curvature of the side of the leg, and are separated each from the other in the center of the said leg to form a guide opening or slot 8. The lugs 6, 6 are cut away on the under side to form stops 9, 9, against which trunnion extensions 10, 10 strike when the mounting is raised from the position shown in full lines to that shown in dotted lines in Fig. 1 of the drawings. The lug 7 is extended across the leg 5, and is shaped to receive a groove formed in the upper surface of a bracket 11. The bracket 11 is formed with separated hook-like exten- Specification of Letters Patent.

sions 12, 12, the upper surfaces of which are formed to rest parallel with the under surfaces of the lugs 6, 6 when the said bracket is secured in position. The hook-like extensions 12, 12 are separated to form a channel 13 to guide the mounting for the caster as the same is moved from the inoperative to the operative position, and to form a seat therefor when in the operative position. The body portion of the bracket 11 is rounded to the inner curvature of the leg 5, and is perforated to receive a screw bolt 14. The screw bolt 14 is held by a screw nut 15. The nut 15 is prevented from turning by downwardly extending walls 16 and 17 and the side walls of the body portion of the bracket 11. The four walls form a square recess adapted to hold the nut 15. The walls 16 and 17 serve the further purpose of forming seats to receive the thrust of the caster mounting. The wall 16 is mounted in set relation to the slots formed by the faces of the lugs 6, 6 and the upper surface of the hook-like extensions 12, 12, The depending edge of the wall 16 is located with reference to the slots in such position that when the trunnion extensions 10, 10 are at the lower end of the said slots the end of the caster mounting will extend below the wall 16, as illustrated in Fig. 1 of the drawings. In this position the caster mounting and the caster are maintained in the raised and inoperative position shown in the said figure of the drawings.

The wall 17 is extended downwardly, and at the lower end thereof is provided with an outward edge 18. The edge 18 is formed square to receive and form a seat for a groove 19 formed in the body of the mounting 20. The caster mounting 20 is provided with a body portion from the rear whereof is extended a tail piece 21, from the sides of the end of which are projected the trunnion extensions 10, 10. The groove 19 is cutlaterally across the body portion of the mounting 20. The groove is formed substantially as shown in Fig. 2 of the drawings, the outer wall whereof overhanging the edge 18. When the edge 18 is in the groove 19, as shown in Fig. 2 of the drawings, the trunnion extensions 10, 10 rest against the stops 9, 9 of the lugs 6, 6. In this position the mounting 20 supports the stove leg 5, carrying the weight in the groove 19 and on the trunnions 10, 10.

A caster wheel 22 is mounted on pivotal bearings 23 within the usual yoke 24. 1 1 spindle 25 is extended upward through the perforation formed in the mounting 20, and headed or otherwise secured in the said mounting. The spindle 25 is arranged to freely revolve within the mounting 20.

It will be observed that when the bracket 11 is disengaged from the leg 5, the mounting 20 and caster wheel connected therewith, may be readily and freely separated, no engagement existing which prevents the tail piece 21 from being removed from between the extensions 12, 12. hen, however, the bracket 11 is secured in the position as shown in the drawings, the separation of the mounting 20 from the bracket 11 is rendered impossible by the interposition of the stops 9, 9 of the lugs 6, 6.

When a stove is equipped with legs constructed and arranged with caster mountings and casters, as shown in the accompanying drawings, the operation is as follows: When it is desired to move the stove the casters are dropped from the position shown in Fig. 1 of the drawings by raising the mounting 20 until the end of the tail piece 21 clears the wall 16, dropping forward on to the floor. By raising the leg 5, the mounting 20 and caster are permitted to drop to a vertically dependent position, the trunnion extensions 10, 10 passing to the lower end of the slot formed by the lugs 6, 6 and the extensions 12, 12. In this position the mounting 20 is easily swung to the forward position in which the edge 18 of the wall 17 enters the groove 19. In this posi tion the leg 5 is lowered, bringing the caster wheel 22 in contact with the floor. The weight of the stove being now exerted upon the mounting 20, the latter takes a seat upon the bracket 11, and the lugs 6, 6, by sliding until the edge 18 strikes against the forward wall of the groove 19, and the trunnion extensions 10, 1O strike upon the stops 9, 9 of the lugs 6, 6. In this position the caster, and the mounting are, to all intents and purposes, rigidly set, and the stove may be moved to any desired posit-ion, the caster wheels 22 operating in the manner usual to them.

Having moved the stove to the desired position, and wishing to discontinue the use of the casters, the operation just above described is reversed. That is, the leg 5 is raised. The weight of the mounting 20 and caster carried thereby moves the said mounting downward until the forward wall of the groove 19 clears the edge 18, and the caster and mounting swing to the vertical dependent position, the trunnion extensions 10, 10 passing to the lower end of the slot. formed by the extensions 12, 12 and the lugs 6, 6. In this position the mounting 20 is moved to one side, and the leg 5 is lowered until the foot thereof rests upon the floor.

The mounting 20 and the caster, are, during the operation, either by hand or automatic ally, moved to one side away from the front of the leg. The mounting is now raised to the position shown in dotted lines in Fig. 1, in which the trunnion extensions are lifted so that the extreme end of the tail piece 21 avoids the wall 16. lVhen turned, the mounting is dropped until the extreme end extends under and into engagement with the lower edge of the wall 16. In this position the mounting 20 and the caster will remain until the operation described in the previous paragraph be put into execution.

lVhen the caster is in operation it will be observed that the mounting 20, is snugly held between the side walls of the bracket, and thus is prevented from any lateral movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
